4.7 й
й , к к , и и, з з keys
The arrow keys are used to move the cursor and edit numeric values.
The è and ç keys move the cursor side to side within a cursor field. They can be used to position the cursor over a digit within
the field to modify. Once the cursor is over the desired digit, use the é or ê key to increment or decrement that digit.
Pressing the é key increments the digit under the cursor and has the same effect as rotating the knob clockwise 1 tick. Pressing
the ê key decrements the digit under the cursor and has the same effect as rotating the knob counter-clockwise 1 tick.
While a numeric value is being typed in, you can use the ç key as an erase key. Pressing this key erases the last digit entered,
allowing you to correct typing mistakes.
All arrow keys have an "auto repeat" feature. By holding down the key, the key will repeat continuously until released. This
makes it more convenient to quickly sweep a value or move the cursor within a field.
These keys are also used to select a new operating mode after the Mode key is pressed. The arrow keys are then used to select the
mode indicated by the blue text beneath the key.
In DTMF Generation mode, these keys specify DTMF digits A,B,C,D which are signaling tones used in the telephone network but
not found on a typical telephone. For more information, refer to the chapter on DTMF Generation mode.
4.8 Clear key
While the cursor is within a numeric field, the Clear key erases all digits within the field, allowing the user to start over when
entering a value.
This key is also used to select the "Other" mode after the Mode key is pressed once. By selecting Other Mode, a menu of
extended modes for the 630 is presented. See the chapter on Changing Modes.
4.9 MHz/dBm, KHz/Vp-p/Sec, Hz/mVp-p/mS keys
These keys are used to select the units for a numeric value once it has been typed into a parameter field. After entering all digits
for a value, you must press one of these keys to complete the entry of the value. In other words, these keys serve as an "enter" key
since a value being edited in a cursor field is not accepted and processed until one of these keys is pressed.
After pressing one of these keys, the 630 will make a double clicking noise to indicate that the value has been accepted. If the
entered value is outside the allowable range for the field, the 630 will give an error beep and set the value to its upper or lower limit.
To enter a value in Volts or milliVolts, use the Vp-p and mVp-p keys, respectively.
When entering a value that has units not listed on the key (i.e. percentage, ohms, etc.), any one of these three keys will work as an
enter key.
4.9 One Touch Mode Keys
These keys immediately switch the function generator to the operating mode indicated on the key. These keys make it more
convenient to switch to frequently-used operating modes.
